c# - XNA 3.1 中的多个模型

Question

我有 XNA 3.1，如何在 xna 3.1 中加载多个模型以从数组或按钮单击或切换任何内容进行渲染？我只需要加载多个 3d 模型进行渲染。

我在哪里获得代码，但此代码在 4.0 中

Model[ ] modelArray;

protected override void LoadContent() 
{
   modelArray = new Model[3];
   modelArray[0] = Content.Load<Model>("model1");
   modelArray[1] = Content.Load<Model>("model2");
   modelArray[2] = Content.Load<Model>("model3");
}

protected override void Draw(GameTime time)
{
    GraphicsDevice.Clear(Color.LightBlue);
    foreach (Model m in modelArray) 
    {
       foreach (BasicEffect be in m.Effects) 
       {
          be.World = YOURWORLDMATRIX;
          be.View = YOURVIEWMATRIX;
          be.Projection = YOURPROJECTIONMATRIX;
       }
       m.Draw();
    }
    base.Draw(time);
}

此行中发生错误，它们向我显示此错误：

ERROR1:'Microsoft.Xna.Framework.Graphics.Model' does not contain a definition for    
   'effects' and no extension method 'effects' accepting a first argument of type  
         'Microsoft.Xna.Framework.Graphics.Model' could be found (are you missing a 
       using directive or an assembly reference?) 

Draw中也有同样的错误：

  'Microsoft.Xna.Framework.Graphics.Model' does not contain a definition for 'draw' 
       and no 
    extension method 'draw' accepting a first argument of type 
    'Microsoft.Xna.Framework.Graphics.Model' could be found (are you missing a using 
      directive or an assembly reference?) 

在这些行中

m.Effects
m.Draw();

有什么解决办法吗？

Answer 1

绘图过程不同，试试这个：

foreach (Model m in modelArray) 
{
   foreach (ModelMesh mesh in m.Meshes)
   {
       foreach (BasicEffect effect in mesh.Effects)
       {
          be.World = YOURWORLDMATRIX;
          be.View = YOURVIEWMATRIX;
          be.Projection = YOURPROJECTIONMATRIX;
       }
       mesh.Draw();
   }
}

参考MSDN。
